them, variants therefrom. The pieces used in such machines, e. g., thematrices of the Well Aknown matrix composing and line casting matrix isaat oblong plate, the opposite v20 [top and bottom.

lshorter edges of which are respectively its A plate. constitutes thebody of a matrix and has a lug projecting from each corner: in its ownplane.V The two top lugs are of the same size with their top faces flushwith the top of a plate and the bottom faces of the bottom lugs, flushwith the bottom of a plate. i

`The above mentioned 4plurality of I'faces imposes the followingrequirements----irst, means for adjusting the level of each matrix atthe place of composition, so as to place the desired Variant face in thecomposing f line.; second, means for holding all the matrices in thetypographical line, in the respective positions during the time that-the said line 1s being used, e. g. having a ilme rproduced from lit bycasting as in the machine instant-ed; and thirdly, means for restoringall the adjusted matrices to the normal level so` as to adapt them to bedealt with by the distributor. These last mentioned means consist in4the machine instanced, ina leveling bar and the means for holdingthendjusted matrices being, a ledge for each level, engaging" undertheir bottom lfront lugs, and automatically retractable fromthereunder-,as the means which hold allthe matrices moves away from the,fusing position toward the distributor. justing motiony above mentionedas 'being made ai the place of composition,is-an upward one and when 'ithas been' made, the bottoni-edges ofithortoplugs of the adjusted,

The adf those of the unadjusted, i. e., normal matrices, are either inthe same horizontal plane or they overlap each other. Several meti-nshave been proposed to meet these requirements, and at least one meetineach requirement, is in use in the mac iinc instanced when it isequipped with matrices having two faces. The means for holding allthematrices in the line, in' the respective positions, during the timethe said line is being used; area ledge engaging under each top lug of.the normal z'. e., unadjusted matrices and a third ledge engagingIunder the front bottom lug of each variant t'. e., adjusted matrix, sothat it is not the whole of the last mentioned lug but only its bottomface that can affect such holding. But these bottom facesfget worn byrepeatedY hard contacts Withcertain parts of the machine, to an extentsufhcient to put the respective variantfaces out of adjustment when thesaid bottom faces are 0n 75 the ledge.

The object of the `present invention is to prevent the wear justdescribed so thwarting the desired adjustment' of the variant" faces. Ithas already been proposed to prevent this thwarting by prolonging thethird ledge and front bottom lug, either or both, in such `a way thatthe lug shall either present to the ledge, a portion of bottom face thathas not como into such contact with any part of the machine, or that theledge shall engage with the' foot of the body Iof the matrix, in eitherof which cases, no wear which the bottom face of the lug may havesuffered, can be material. It has also been proposed to hold theadjusted z'. e., variant matrices during the time the typographical lineis being used, by a rail automatically engaged under each of their toplugs andrantomatically disengaged therefrom after si'ieh 95 use, bothengagement and'fdisengagement bei-ng in the direction of the length ofthe two rails; or by a ledge standing in front of the line and soconnected with the same for restoring all the adjusted matrices to thenormal level, that it automatically engages [in a'notch commomto all thefront top lugs of the said matrices andis automatically disi engagedtherefrom as the typographical line ismoved away toward thedistributer.

c iiihepresent invention consistsv in reducing the vertical dimension ofthe top front l'ug of-each matrix more or less, say by about one half,so that there shall be a space between the top front lugs of theadjusted matrices and those of the normal matrices, this space embracinga ledge having the functions of the third ledge already described andsuitably positioned to be so embraced. Thus the lug surface that engagesthe ledge is one which enjoys, by reason of its being a bottom face of ato lug, immunity from the wear described. I there is a plurality ofvariant faces, there is a corresponding plurality of reduced top frontlugs and spaces arranged columnwise on the matrices. The ledge justdescribed is a single one and will in any case be embraced by the lowestspace. But it will be understood that a greater number of ledges may beprovided to correspond to the number of variant faces on the matrices.

The accompanying figures illustrate two preferred constructional formsof the invention when applied to a machine of the kind instanced andequipped with matrices having one variant face.

Referring to them, Figure 1-is a vertical section looking from the righthand side of the machine and showing the parts of one constructionalform in the casting position; Fig. 2, a like section showing the variantface pieces restored to the normal level; Fig. 3, a side elevation ofone form of matrix; Fig. 4, a section as Fig. 1, of the other form; andFig. 5, a side 'elevation of a modified form of matrix.

a is the mold wheel, carrying the mold block r b having the mold cavityb1 against which the head c of the so called first elevator is holdingthe typographical line consisting of matrices d both normal and variant,the normal matrices engaging by their top front lugs on a rail m, whilethe bottom rear lugs 'i of both normal and variant matrices engageloosely, z'. e., without being held, respectively in a plate c fast tothe mold block b and under.

the latterl The ledge e is loosely connected to a lever f and slideshorizontally in the head c, being protruded by a spring g intothepathiof the adjusted line before it is pushed intor the head c. Asthe said line is being moved toward the distributer (not shown), theledge e is disengaged from the variant matrices, by the engagement ofthe lever f with an abutment n on the machine, whereupon the saidmatrices are restored to the normal level partly by their own weight andpartly by an overlying bar o, all as heretofore. v

Figs. l and 3 to 5 show the upper face d1 of the normal matrices and thelower faces d2 of the variant matrices -registering properly with themold cavity b1 and also that relying upon the engagement of the bottomof the front bottom lugs of the variant matrices With the top of anunderlying ledge to keep their lowerfaces d2 in register with the moldcavity b1 must fail proportionately to the amount of wear which thosebottoms had suffered.

According to the constructonal form shown in Figs. 1 to 3, the verticaldimension of the top front lug L of over matrix in a font is reduced atits bottom ace, as a comparison of the said lug in Fig. 3 with the toprear lug, shows, so that the top front lugs of the normal and variantmatrices of the typographical line will stand in two parallel rows asindicated in Figs. l and 4f, with a space p between them. The knownledge e 1s now so positioned in the head c as to register with thisspace, so that when the said line is pushed into the' head c, the bottomfaces of the lugs It on the Variant matrices, will engage on and be heldby the ledge e in the line casting position, while the lugs .71, on thenormal (or any matrices occupying a lower level) will stand under underthe said ledge and clear of it.

y The constructicnal form illustrated in Fig. 4 and 5 diders from theone just described only in the vertical dimension of the top front lugs71, being reduced at its top f ace. The way in which the presentinvention deals with a font having a plurality of variant lfaces, vhasbeen already explained. The position ofthe second lug /t required by anadditional variant face, is indicated by dotted lines in Figs 3 and 5. l

The terms matrix, matrices are to be understood throughout thisspecification and the following clalms as respectively includlng typedie, type dies.

Having described my invention, I declare that what I claim and desire tosecure by Letters Patent is':-

1. In means for holding the variant face matrices of a mixedtypographical line in position for being used in a line producingmachine, the combination with a font of matrices having reduced lugs sopositioned thereon tbatthe vertical adjustmentof the matrices accordingto face, arranges the said lugs in rows separated by a space, of a ledgeupon which the said lugs of the elevated matrices rest and under whichthose of the unelevated matrices stand clear.

2. In means for holding the variant face matrices of a mixedtypographical line in position foribeing used in-a line producingmachine, the combination with a font of matrices having reduced lugs sopositioned thereon that the adjustment of the matrices according toface, arranges the said lugs in rows separated by a space, of a ledgeupon which the coperating row of ln gs on the adjusted matrices rest andunder which those of the matrices at a lower level in the line, standclear.

3. In a typographical. casting machine, the combination of a mold, aline of matrices each formed with a projecting ear at its iso position.

4. In a typogra hical machine, comprising matrices each 'ormed with aprojecting ear at its upper end, the combination of the mold, and thefirst elevator to present the matrices to the mold and movable to eiecttheir lalinement therewith, the said elevator being provided With aledge to engage beneath the-upper ear of the matrices in elevatedposition, and the matrices having their projecting ears of reduced sizeand so located as to avoid the supporting ledge when standing in thelower posit-ion.

5. In a typographical machine, the combination of a line of matriceseach formed with a projecting ear at its upper end, and means forsupporting the matrices at different levels,.the said means comprising aledge to engage beneath the upper ears of the matrices in elevatedposition, and the matrices having their projecting ears of reduced sizeand so located as to avoid the supporting ledge when standing in thelower position.

6. In a typographical machine, the combination of a line of matriceseach formed with a rojecting ear at its upper end, and means 'orsupporting the matrices at different levels, the said mean comprising aledge to engage beneath the upper cars of the matrices in elevatedposition, and the matrices having the upper portions of their ears cutaway to avoid said ledge when they-stand in the lower position,

In Witness whereof I have hereunto set my hand in the presence ot' twowitnesses.
